An insert member (100) heated by a heating device (13) is conveyed, by means of a conveyance device (12), into a mold (51). Next, shaping is performed on the insert member (100) inside the mold (51), with the mold (51) being open by a minute distance. A molding material (91) is injected into the mold (51) and pressed while closing the mold (51) which has been open by the minute distance to thereby mold a molded article (80) including the insert member (100).

An injection moulding apparatus and method for producing a moulded article is disclosed herein. In a described embodiment, the method comprises: (i) securing a layer of film to a part of a first mould half at step 504; (ii) adjusting relative position of the first mould component and a second mould component to an initial moulding position at step 506 to define a mould cavity; (iii) injecting molten moulding material into the mould cavity at step 508 to enable the molten moulding material to contact the layer of protective film; (iv) moving a movable core at step 510 to compress the molten moulding material in the mould cavity; and (v) cooling the compressed molten moulding material at step 514 to bond the layer of film to the cooled moulding material to form the moulded article.

The invention relates to a rotor for a compressible fluid pump, in particular a blood pump that can be introduced through a blood vessel into a patient's body, wherein said rotor comprises one or more conveying elements (15), is compressible and expandable between a first compressed state and a second radially expanded state, is made at least partially from a plastic reinforced with reinforcing elements, in particular fibers (10, 11, 13, 18, 19, 55, 56, 62, 63) and is provided for rotation about an axis of rotation (14). According to the invention, the rotor is tensioned in the first, compressed state and free from external stresses in the second, expanded state. A third state exists, which the rotor (42) occupies in the operating state under load. The reinforcing elements, in particular fibers, extend in the rotor in the third state at least in sections in a stretched manner.

A method and device for producing an optimized neck contour on preforms below the neck which is optimal for subsequent stretch blow molding. The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding. The thin-walled geometry on the preform can be produced outside of the mold during post-cooling by embossing. The preform is then removed in a cooled receiving sleeve and is cooled in the body by intensive contact cooling while no cooling contact is made with the preform neck due to the initial position of the embossing element. Due to the reheating of the neck they can be mechanically deformed into a new geometry advantageous for blow molding and thus wall thickness can be influenced.

Disclosed herein, amongst other things, is a molding system (100) comprising control structure that includes a mold (120) that is configured to mold a molded article (180), a controller (170) with which to control the operation of the molding structure, and a vision system (174) with which to appreciate a parameter of the molded article (180) for control of molding system (100).

The present invention relates to a polylactic acid resin composition and a molded product using same. Since the polylactic acid resin composition according to the present invention has excellent environmental friendliness and biodegradability, has excellent heat resistance characteristics due to high heat deformation temperature (HDT), and may be injection molded within a commercially reasonable cycle time due to high crystallinity and crystallization rate, it is suitable for the preparation of a molded product.

A method for manufacturing a spline telescopic shaft according to the present disclosure includes a toothless portion forming step of forming a toothless portion in one of an external tooth of a shaft body and an internal tooth of a tubular body, a resin layer forming step of forming a resin layer by arranging one of the shaft body and the tubular body in a mold including a cavity and injecting a resin into the cavity, the cavity being included in a flat receiving surface that faces tooth flanks of one of the external tooth of the shaft body and the internal tooth of the tubular body, and a cooling step of cooling one of the shaft body including the resin layer and the tubular body including the resin layer to form a lubricant reservoir in the resin layer.

Disclosed is an overmolding device of a cosmetic vessel including a cosmetic vessel made of glass, a cooling means for cooling the inside of the cosmetic vessel, and left and right outer molds and overmolding an outer shape of the cosmetic vessel with the cosmetic vessel and the cooling means interposed therebetween. According to the present invention, it is possible to prevent breakage of the vessel due to a molding temperature by cooling the inside of the cosmetic vessel by the cooling means at the time of overmolding of the cosmetic vessel such as a perfume bottle.

A cushioned article includes a cage and a compressible material. The cage has at least one opening, an interior volume, and an outer surface. The at least one opening provides a passage from the outer surface to the interior volume. The compressible material extends through the at least one opening in the cage. A method for manufacturing a cushioned article includes providing a mold having at least one cavity, placing a cage within the mold, and injecting a compressible material into an interior of the cage. The cage includes at least one opening. A portion of the compressible material flows through the at least one opening in the cage and fills the at least one cavity of the mold. One or more shields may be connected to the cage before injection. The shields may be removed with the cage and heat treated with the shields still connected to the cage.
